OK it's been done hundreds of times, I'm sure.
Sprout used to be a terrible sleeper, now I'd say average for his age. Dummies are strictly for sleep times ony or very long car journeys (e.g the 8 hour trip to Cornwall). But he's an addict. Until a couple of days he used to demand ask for at least two. So far have cut it down to one and stopped giving him the dummy until he's actually in the cot, rather than during story when he settles.
What next? Cold turkey? More gradual tactic? CM will do as I ask, grandma (regular childcare and sleepovers) won't be able to refuse him so whatever needs to work quick on my days off.
Giving up now because I'd intended to earlier but family situation meant I didn't have the strength. 11 weeks pregnant and can't face having two with dummies somehow. 2 in nappies I can face, but 2 with dummies pushes the wrong buttons!
